Use 2nd Last API Version

[msadlows]

While I know we can easily set the API version, the defult behaviour is to use the oldest supported API version. Trouble with this is that Shopify is now throwing all sorts of error notices in the app dashboards when they see a soon-to-be-depreceated API being used. If using the 2nd oldest, this won't ever be the case. More of a thought then a specific issue.

I've just received an deprecated API notice from Shopify as well. But the timing on it is all wrong... that's another story.

It's claiming that I should be using API verision 2020-07. I'm going to manually pass it as a string to the constructor option apiVersion. If that doesn't do the trick I'll report back.
